At some point, Hall began working out in the offseason with Yankee hitting coach and noted resurrectionist Kevin Long, who’s done a magnificent job of straightening out both Nick Swisher and Curtis Granderson over the past couple of years. Traded to Boston for Casey Kotchman, Hall found plenty of playing time in left field, at second base and in spot duty at five other positions (including an inning on the mound!) for the injury-wracked Sox, and he turned in a season whose overall line is almost a dead ringer for his career numbers, hitting .247/.316/.456 with 18 homers in 382 PA. Underneath the hood, he had a strong rebound against righties at the expense of a brutal year against lefties, some of which may have had to do with habits developed to succeed in Fenway; he took advantage of his natural pull tendency and hit a lot of fly balls off of and over the Green Monster.

In all, Hall would bring an intriguing skill set to the Yankees, as well as liabilities. Unlike Peña, he can competently fill in at six positions (second, short, third, and the outfield) for weeks at a time in the event another player hits the DL, and he can pop a ball out of the yard every now and then. But he’s got a history of contact woes and widely variable performances; anyone who’d be surprised if he were to be suddenly released in June while hitting .141 in minimal playing time because he’s suddenly forgotten how to hit to the opposite field hasn’t been paying attention. Still, for a few million dollars — and particularly with Long on hand to monitor his swing — he’d be a big upgrade on what the Yankees had on the bench last year.

Upton is one of the most talented young players in baseball. The first overall pick of the 2005 draft, he tore the cover off the ball at two levels at 19 and made his major-league debut that same year. His age-20 season wasn’t great by the standards of right fielders, but was fantastic given his age. In 2009, he followed with one of the better seasons ever produced by a 21-year-old. His hitting .300/.366/.532 in the majors when most players his age were in Single- or Double-A compared favorably with any number of current or future Hall of Famers, a list stretching from Ted Williams and Jimmie Foxx to Alex Rodriguez and Albert Pujols.

This season was a different story. Like his older brother B.J., who had a big season at 22 and then went backwards, Upton disappointed with a .273/.356/.442 season in 2010. Ironically, if he had been a 22-year-old rookie, we might look at the season and say, “Not bad. A little inadequate for a right fielder, but he’s only 22 and maybe he builds on this.” Upton had already set a higher bar for himself, so his season was inevitably seen as a letdown.

It is difficult to pinpoint is the reason why Upton had such an off year, but at 23 it is far too soon to give up on him. He has speed, power, good speed in the outfield, and is probably still several years from the center of his prime. He is also right-handed, and though he didn’t hit lefties very well in 2010, in 2009 he murdered them, hitting .377/.445/.762. In games started by left-handers, the Yankees were 31-27 (.534) versus 64-40 against right-handers (.615).
